Having owned an Avenger I do have a bit of experience. It helps a lot to learn to drive an Argo. These machines are not true six/eight wheel drive, but one-side drive. This is due to the open differiential they have. One side spins while the other side does nothing. Thus one must apply brakes to the side that spins, which "forces" power to the othet side. In essence, the driver turns left and right quickly and repeatedly. Not always but it does help a lot.
Perhaps this will help in those tough spots. Enjoy.
